Abstract
Description
L'invention concerne un dispositif extrudeur notamment de pates alimentaires pour la production de confiseries. The invention relates to an extruder device in particular for pasta for the production of confectionery.
On connais déj des extrudeurs à pites alimentaires pour la production de chewing-gum, pate à mâcher, etc. We already know food pellet extruders for the production of chewing gum, chewing dough, etc.
Ces extrudeurs comprenaient une ou plusieurs vis d'extrusion travaillant seules.These extruders included one or more extrusion screws working alone.
Une première amélioration d'un tel dispositif a été de compléter les vis d'extrusion par des rouleaux alimentaires prenant en charge la pâte alimentaire et l1ame- nant sur les vis d'extrusion. A first improvement of such a device was to complete the extrusion screws with food rollers taking charge of the food dough and the feeder on the extrusion screws.
Les dispositifs extrudeurs traditionnels comportent donc, d'une manière connue, un corps de presse dans lequel sont logés des rouleaux alimentaires rotatifs et des vis hélicoidales transportant la pite en direction d'une filière d'extrusion, chaque rouleau et chaque vis correspondante ayant un sens de rotation identique. The traditional extruder devices therefore comprise, in a known manner, a press body in which are housed rotary food rollers and helical screws transporting the wedge towards an extrusion die, each roller and each corresponding screw having a identical direction of rotation.
Cependant, de tels extrudeurs traditionnels présentent un certain nombre d'inconvénients tels qu'un coefficient de remplissage peu élevé pour l'alimentation des vis. En outre, ces extrudeurs nécessitent une grande puissance donc beaucoup d'énergie ce qui augmente le prix de fabrication. Enfin, ces extrudeurs déjà connus sont d'un montage plus complexe et donc d'un prix de revient plus élevé. However, such traditional extruders have a certain number of drawbacks such as a low filling coefficient for feeding the screws. In addition, these extruders require great power and therefore a lot of energy, which increases the manufacturing price. Finally, these already known extruders are of a more complex assembly and therefore of a higher cost price.
La présente invention a pour but de remédier à ces inconvénients et se propose de créer un dispositif extrudeur suivant lequel l'alimentation des vis se fait avec un coefficient de remplissage élevé et nécessitant une puissance moindre. The present invention aims to remedy these drawbacks and proposes to create an extruder device according to which the screws are supplied with a high filling coefficient and requiring less power.
La présente invention a également pour but de créer un dispositif extrudeur dont le montage mécanique et les pièces mécaniques utilisés soient de conception plus simple et moins nombreuses ce qui abaisse notablement le prix de revient de l'extrudeur tout en assurant une productivité accrue. The present invention also aims to create an extruder device whose mechanical assembly and mechanical parts used are of simpler design and fewer which significantly reduces the cost price of the extruder while ensuring increased productivity.
A cet effet, la présente invention concerne un dispositif extrudeur notamment de pates alimentaires comportant un corps de presse dans lequel sont logés des rouleaux rotatifs d'entrainement recevant la pâte à partir d'une trémie d'alimentation et transférant cette patte vers des vis hélicoidales de transport en direction de la filière d'extrusion, dispositif caractérisé en ce qu'il comporte au moins un rouleau dgalimentation et une vis de transport, le rouleau étant animé d'un mouvement de rotation autour de son axe dans un sens détermine inverse de celui de la vis de transport. To this end, the present invention relates to an extruder device in particular for pasta comprising a press body in which are housed rotary drive rollers receiving the dough from a feed hopper and transferring this tab to helical screws transport in the direction of the extrusion die, device characterized in that it comprises at least one feed roller and a transport screw, the roller being driven in a rotational movement around its axis in a direction which determines the opposite of that of the transport screw.
Suivant une autre caractéristique de l'invention, le dispositif comporte deux rouleaux d'alimentation de la pâte, disposés au-dessus de deux vis de transport tournant en sens inverse l'une de l'autre, les rouleaux étant entratnés dans un sens de rotation inverse de celui des vis de transport. According to another characteristic of the invention, the device comprises two rolls for feeding the dough, arranged above two transport screws rotating in opposite directions to each other, the rollers being driven in a direction of reverse rotation to that of the transport screws.
La présente invention sera mieux comprise à l'aide d'un mode de réalisation dlun dispositif extrudeur conforme à l'invention, représenté schématiquement, sur les dessins ci-joints dans lesquels
- la figure 1 est une vue de côté du dispositif extrudeur,
- la figure 2 est une vue en coupe de face du dispositif extrudeur.The present invention will be better understood using an embodiment of an extruder device according to the invention, shown diagrammatically in the accompanying drawings in which
FIG. 1 is a side view of the extruder device,
- Figure 2 is a front sectional view of the extruder device.
Selon la figure 1, le dispositif extrudeur 1 comporte un corps de presse 2 dans lequel est monté au moins un rouleau d'alimentation 3 monté sur des paliers 4, 5. According to FIG. 1, the extruder device 1 comprises a press body 2 in which is mounted at least one feed roller 3 mounted on bearings 4, 5.
Au moins une vis de transport 6 htllicordale est disposée à l'intérieur du corps de presse 2 sous le rouleau d'alimentation 3. Selon d'autres modes de réalisation, il est parfaitement possible d'imaginer que le rouleau 3 et la vis 6 comportent des axes situés dans le même plan horizontal. At least one horizontal transport screw 6 is placed inside the press body 2 under the feed roller 3. According to other embodiments, it is perfectly possible to imagine that the roller 3 and the screw 6 have axes located in the same horizontal plane.
Conformément au dispositif 1, la patte alimentaire est introduite selon la flèche F verticalement en direction des rouleaux 3. Les rouleaux d'alimentation 3 entraînent la patte alimentaire sur les vis 6 hélicordales d'où la patte est extrudée conformément à la flèche F, au niveau de la sortie 7. Il est possible de monter une chambre de compression sur la sortie 7, cette chambre de compression étant adaptée au produit extrudé. In accordance with device 1, the food tab is introduced along arrow F vertically in the direction of the rollers 3. The feed rollers 3 drive the food tab on the helical screws 6 from which the tab is extruded in accordance with arrow F, at level of the outlet 7. It is possible to mount a compression chamber on the outlet 7, this compression chamber being adapted to the extruded product.
Le point le plus important du dispositif extrudeur 1 est que le sens de rotation des rouleaux d'alimentation 3 soit un mouvement inverse de celui des vis héli coidales 6. The most important point of the extruder device 1 is that the direction of rotation of the feed rollers 3 is a reverse movement to that of the helical screws 6.
Selon la figure 2, le dispositif 1, vu de face, comporte dans la partie supérieure du corps de presse 2 deux rouleaux d'alimentation 3 dont le sens de rotation autour de leur axe est conforme aux flèches H et H', les deux rouleaux cote à côte étant en rotation en sens inverse l'un par rapport à l'autre. Dans ce mode de réalisation particulier les rouleaux présentent également un écart entre eux prédéterminé susceptible d'améliorer l'alimentation en pâte alimentaire des vis 6. According to FIG. 2, the device 1, seen from the front, comprises in the upper part of the press body 2 two supply rollers 3 whose direction of rotation about their axis conforms to the arrows H and H ', the two rollers side by side being rotated in opposite directions to each other. In this particular embodiment, the rollers also have a predetermined gap between them capable of improving the supply of food paste to the screws 6.
Selon ce mode de réalisation particulier les vis 6 hélicoldales sont disposées en-dessous des rouleaux 3. According to this particular embodiment, the helical screws 6 are arranged below the rollers 3.
Elles sont en rotation autour de leur axe selon les flèches
Ket K', c'est-à-dire dans un sens inverse l'une de l'autre.They rotate around their axis according to the arrows
Ket K ', that is to say in an opposite direction to each other.
Les vis 6 sont en outre placées l'une à côté de l'autre de telle sorte que leur périphérie respective vienne à fleur.The screws 6 are also placed one next to the other so that their respective periphery comes flush.
Le point essentiel de la présente invention réside dans le fait que chacun des rouleaux d'alimentation 3 est mobile en rotation suivant un sens de rotation inverse du sens de rotation de la vis 6 disposée au-dessous de lui. The essential point of the present invention resides in the fact that each of the feed rollers 3 is movable in rotation in a direction of rotation opposite to the direction of rotation of the screw 6 arranged below it.
Ainsi, conformément à l'axe de symétrie X-Y, les rouleaux 3 ont un sens de rotation inverse de celui des vis 6. Les sens de rotation inverses de chacun des rouleaux 3 par rapport aux vis 6 assurent une meilleure alimentation en pâte et un coefficient de remplissage plus élevé En outre, le dispositif 1 est d'une conception simple et d'un montage mécanique aisé ce qui permet également d'abaisser le prix de revient de l'en- semble du dispositif.Thus, in accordance with the axis of symmetry XY, the rollers 3 have a direction of rotation opposite to that of the screws 6. The reverse directions of rotation of each of the rollers 3 relative to the screws 6 ensure a better supply of dough and a coefficient of higher filling In addition, the device 1 is of simple design and easy mechanical assembly, which also makes it possible to lower the cost price of the whole of the device.
Selon ce mode de réalisation particulier, le dispositif 1 comporte deux rouleaux et deux vis mais il est possible d'imaginer une expression plus simple du dispositif ne comportant qu'un seul rouleau 3 et une seule vis 6 dont les sens de rotation sont inverses. Normalement, les vis ont des axes parallèles et fixes ; elles sont entratnées en rota- tion par un dispositif mécanique situé à leur extrémité amont. According to this particular embodiment, the device 1 comprises two rollers and two screws but it is possible to imagine a simpler expression of the device comprising only a single roller 3 and a single screw 6 whose directions of rotation are opposite. Normally, the screws have parallel and fixed axes; they are rotated by a mechanical device located at their upstream end.
Les rouleaux peuvent avoir des axes parallèles dont l'écartement est variable soit par le réglage de l'un ou des deux arbres des rouleaux. L'axe du rouleau peut également Btre flottant (liaison élastique par rapport au corps de presse).The rollers can have parallel axes whose spacing is variable either by adjusting one or both of the roller shafts. The axis of the roller can also be floating (elastic connection with respect to the press body).
L'entraînement des rouleaux est assuré par leur arbre, mais il n'est pas nécessaire que les deux rouleaux soient entraînées par leur arbre. L'un des deux suffit. L'autre tourne alors grâce à la seule force dlentraSnement communiquée par la pate et induite par le rouleau moteur. The rollers are driven by their shaft, but it is not necessary for the two rollers to be driven by their shaft. One of them is enough. The other then turns thanks to the only drive force communicated by the dough and induced by the drive roller.
